I'm using Jersey Client 2.29 I believe.
When handling a request the server responds with Content-Type = application/ (of course that is a bogus value it is supposed to be application/json). jersey blows up because it can't parse the subtype of the media type:

I have no control of this 3rd party server and I have to be able to process this request.
Is there anyway around this?
Some property, setting, registering a custom media type provider, anything?
P.S.
I have successfully used ByteBuddy to redefine this method at runtime and handle the error with some extra special sauce but that is a major hack... I'd love a better option if it exists.
Client Configuration
final Client client = ClientBuilder.newBuilder()
.property(ClientProperties.REQUEST_ENTITY_PROCESSING, RequestEntityProcessing.CHUNKED)
.property(ClientProperties.FOLLOW_REDIRECTS, false)
.sslContext(tls)
.hostnameVerifier(new NoOpHostnameVerifier())
.register(new CookiePersistFilter(NARRATIVE)) // @Priority(HEADER_DECORATOR)
.register(new LoggingFilter(NARRATIVE)) // @Priority(USER)
.register(MyFilter.class) // @Priority(50000)
.register(JsonReader.class)
.register(JsonWriter.class)
.register(HTMLReader.class)
.register(MultiPartFeature.class)
.build();
Filters are executed in this order:
As Paul Samsotha pointed out, I can fix this with a ClientResponseFilter using high priority. Here is one way one could do it.
import javax.annotation.Priority;
import javax.ws.rs.client.ClientRequestContext;
import javax.ws.rs.client.ClientResponseContext;
import javax.ws.rs.client.ClientResponseFilter;
import javax.ws.rs.core.HttpHeaders;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.ext.Provider;
import com.selinc.winchester.common.narrative.INarrative;
import com.selinc.winchester.sentinel.Sentinel;
import com.selinc.winchester.wrestler.ResponsePriorities;
@Provider
@Priority(25000) // Note the priority ordering is reverse of ClientRequestFilter
public final class ResponseHeaderWorkaroundFilter implements ClientResponseFilter
{
@Override
public void filter(final ClientRequestContext requestContext, final ClientResponseContext responseContext)
{
try
{
// Attempt to read the Content-Type header.
responseContext.getMediaType();
}
catch (Throwable error)
{
// On error, set the Content-Type header to some default value.
responseContext.getHeaders()
.putSingle(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON);
}
}
}
